COMBINATION-PLOW.

SPECIFICATION forming part of Letters Patent N 0. 751,630, dated February 9, 1904,

Application filed October 23, 1903. Serial No. 178,277. (No model.)

To aZZ whom it may concern.-

Be it'known that I, GEORGE E. GILL, a citizen of the United States, residing at lVake Forest, in the county of Wake and State of North Carolina, have invented certain new and useful Improvements in Combination-Flows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of my invention is to provide an exceedingly simple and efficient plow comprising a very few parts constructed and arranged so as to require only a few fasteningbolts and which may be conveniently converted from one kind of implement to anotheras, for example, from an ordinary turning-plow to a shovel-plow or to a cultivator, cotton-scraper, or the like.

The invention will first be described with reference to the accompanying drawings, which are to be taken as a part of this specification, and it will then be pointed out more particularly in the annexed claims.

In said drawings, Figure l is a perspective view showing the standard, plow-beam, and handles, without the operative parts, of an implement embodying my invention. Fig. 2 is a perspective view looking at the earth side of the implement, showing the standard equipped with a point or plowshare and moldboard to form an ordinary turning-plow. Fig. 3 is a perspective view looking at the opposite or land side, showing the standard equipped with a cotton-point, small moldboard, and a left sweep. Fig. i is a front view showing the standard equipped with a shovel-point, double moldboard, and side sweeps or scrapers. Fig. 5 is a longitudinal horizontal section through the standard equipped with side sweeps or scrapers. Fig. 6 is an enlarged detail side elevation of the earth side of the standard with the plate or casting used in connection with the side sweep represented in place. Figs.

'7, 8, and 9 illustrate in detail various operative parts.

Referring by specific reference-numerals to the implement illustrated, which is a No. 2 Combination WV. B. Dunn Plow Cos Plow, 1 indicates the plow-beam, 2 denotes the handles, and 3 designates the standard to which the several operative or soil-cutting parts are attached. The standard is shown secured to the plow-beam by means of a stirrup embracing the latter and bolted to said standard, which in this instance is also bent or inclined under the beam to throw the front cutting edge of the plow thereunder or into the medial line of draft. Any suitable fastening device may, however, be adopted. The handlebars are represented brought together near the beam and bolted thereto, while their lower ends are bolted to a rearward part or projection 4 of the standard. This is an advantageous feature of construction, combining simplicity and strength. A metal strip 5 may be secured on the lower side of the handle-bar next the earth side of the implement between said projection 4 of said standard and the beam to prevent wear of said handle-bar by the earth in plowing.

The standard 3 consists simply of a flat member or casting having its lower part conforming to the general shape of the plow, its front inclined and formed with a sloping flange 6 projecting to the earth side, constituting a frog or saddle for attachment of the plowshare, moldboard, or other parts, and its opposite fiat side or face formed with a lower longitudinal rabbet or recess in which the landside 7 is fitted flush with this side of the standard. By virtue of this recess the landside may be secured rigidly in place by a single fasteningbolt, (indicated at 8.)

As an ordinary turning-plow the implement may be equipped with a suitable point or plowshare and moldboard, (designated in the drawings by the numbers 9 and 10, respectively.) The plowshare is of course fitted over the lower end or point of the standard and conforms therewith in shape, having its principal or larger sloping side resting on the lower part of the flange or frog 6 and secured thereon by a single bolt 11 and having its opposite flat side fitted on the flat side of the standard or in the lower rabbet or recess thereof and against the front edge of the landside 7 The said front edge of the landside is also somewhat pointed and the rear edge of the flat side of the plowshare recessed or formed to receive the same, as shown, or, in other Words,

the rear edge of said flat side of the share bears both above and below the front edge of the landside, whereby the share is held rigidly in position against either upward or downward strains. The moldboard rests on the sloping upper part of the flange 6 and is fastened thereon by a bolt 12. The adjacent edges of the plowshare and moldboard are formed correspondingly irregular and fitted together so as to lock the parts in position and render the single fastening-bolts 11 and 12 suflicient. As illustrated, the upper edge of the plowshare has a medial depression and a projection at the front edge or ridge, while the lower edge and. front of the moldboard are formed to correspond. Instead of the moldboard 10 either of the half-fronts or moldboards 13 and 14 illustrated may be substituted, if desired, the latter moldboards being smaller and formed to fit rigidly against the upper edge of the plowshare and in the medial depressions thereof.

To convert the implement into a shovelplow, the plowshare and moldboard described may be detached and the double share 15 and double moldboard 16 may be substituted. These may likewise be secured in place by the single fastening-bolts 11 and 12. One of said parts (here the share) has a medial lug or projection fitting in a corresponding notch or recess in the adjacent edge of the other part to hold them rigidly in place.

In connection with the shovel-plow it is frequently desirable to employ side sweeps or scrapers, such as indicated by the numerals 17 l7 as, for example, when cultivating cot-.

ton or similar growths. These sweeps, which consist of rearwardly-diverging or outwardlyextending wings or blades having thin front or inner ends bent forward for attachment to the implement, may be secured to the standard and to each other by a single longer bolt substituted for the bolt which fastensthe landside to the standard. The sweeps may be secured directly against the opposite sides of the standard, though preferably, as represented, the sweep at one side is fastened against the landside, while that at the other side is secured against a part or casing 18, interposed between it and the standard and suitably formed so as to keep from turning by abutment against the flange 6. In order to prevent the sweeps y from turning or raising under the strain of cultivating, their forward bent parts may have little teats or projections engaging notches or recesses in the landside 7 and part 18 or adapted to engage different notches for adjustment, or any equivalent means might be employed, such as slight coacting corrugated surfaces, which would also provide for adjustments. Either one of the sweeps may of course be used alone when desired.

For cultivating cotton a cotton point 19 or share having a rearward extension is provided to take the place of the regular plowshare 9,

and with said cotton-point one of the smaller 'moldboards 13 or 14 may be used. In connection with such a cotton-point it is generally desirable to employ also a sweep 17 at the 0pposite side of the implement. A double cotton-point 20 is also provided for service when needed, and with this the double moldboard 16 may be used. Different sizes of cottonpoints and sweeps, either single or double, may be provided for cultivating crops of different growths.

It will thus be observed that the plow may conveniently be converted from one kind of implement of tillage to another merely by the changing, substitution, or addition of parts which are adapted for use interchangeably. Other combinations than those described may be formed with the various parts or other parts may be provided for diflerent kinds of cultivation. Thus by means of the one implement described the farmer or planter may prepare the land and cultivate the crop, for this implement takes the place of an ordinary turning-plow and various kinds of cultivators.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is

1. In a plow, the combination of the standard consisting of a flat member having a front sloping flange projecting to its earth side, a casting set against the earth side of the standard and bearing against the under side of said flange to prevent turning thereof, a landside fitted against the opposite flat side, and side sweeps fitted against said casting and said landside, all secured together by a single fastening-bolt, together with a point and moldboard secured on said flange.

2. A convertible plow and cultivator comprising a standard having at the front thereof a lateral flange with seats thereon for a moldboard and share, each adapted to be secured thereto by a single fastening-bolt and cooperating ribs or flanges on the standard, moldboard, and share for sustaining said parts in proper position and relieving strain on said fastening-bolts; the said standard having a rearwardly-extending base with an apertured lug for attachment of a handle, and a recess on the land side thereof to receive a teat upon a detachable cultivating-blade, together with a detachable plate on its opposite side for the attachment thereto of a similarcultivatingblade and recesses in said plate adapted to receive a lug on said cultivating-blade for adjusting the latter on its pivot to change its inclination, and operative parts adapted to be secured to said standard, substantially as described.

In testimony whereof I aflix my signature in presence of two witnesses.

GEORGE E. GILL.
